SPECIFICATION forming part of Letters Patent No. 643,664,-dated February 20, 1900.

Application led May 11, 1899. Serial No. 716,467. (No model.)

To aZZ whom t may concern.-

Beit known that I, WILLIAM H. LYNCHARD, a citizen of the United States, residing at the city of Council Bluffs, in .the county of Pottawattamie, in the State of Iowa, have invented a new and useful Improvement in Printers Quoins and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

My invention is in the nature of a printers quoin or lock-up for forms of type.

It has for its object to furnish a printers quoin consisting of two parallel bars with Wedge-bar adjusted and affixed to said parallel bars and expanded or contracted by a lever operated upon said wedgebar, whereby printers forms are locked, insuring uniform alinement of type.

With this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter described and afterward specifically pointed out in the claims.

In the accompanying drawings, Figure lis a view in side elevation of my device, showing lever in position. Fig. 2 is a top view of my device, looking downward, with all the parts in place and expanded. Fig. 3 is a top View, looking downward, of the wedge-bar, showing mortise for lever. Fig. 4 is a top view of side bars, looking downward, showing grooves for guides to wedge-bar and dovetail mortises. Fig. 5 is a view in side elevation showing position of wedges and lever when my device is contracted. Fig. 6 is a top view of my device when contracted with lever ex tended forward, shown in mortise in Fig. 3, together with fulcrum-notches and parallel side bars, shown in Fig. 4. Fig. 7 is a vertical transverse sectional view of my device, taken on the plane :n x, shown in Fig. 6. Fig. 8 is a. vertical transverse sectional view taken on the plane y y, shown in Fig. 4, showing grooves wherein ianges upon wedges, shown in Fig. 9, slide and hold my device in place. Fig. 9 is a vertical transverse sectional view on the plane 2 z, shown in Fig. 3, and show ing said flanges upon wedges aforesaid. Fig. l0 is a vertical transverse sectional view of combined parallel side bars and Wedges upon bar shown in Figs. 2 and 3, taken on the plane .fr shown in Fig. 2.

Like letters of reference mark the same parts wherever they-occur in the various iigures of the drawings.

Referring to the drawings, a a are the parallel side bars.

b is a wedge-bar upon which wedges c c c are operated.

CZ is a mortise in wedge-bar b.

e e show a lever operated in mortise d.

ffare fulcrum-notches in parallel bars a a, wherein cross-pin g g in lever e e is operated.

7?, h are acute-angled grooves in side bars a ct, and t' 7l are acuteangled anges upon wedges c c.

7o 7c are rivets to bind the flanges upon the wedge-bar b, (shown in Figs. 2, 3, and 6,) which said Wedge-bar and wedges are preferably of metal cast in two sections on plane line o v in Figs. l and 5.

When the parts are placed in the respective positions of grooves h h and lianges t' c' in parallel bars ct a and wedges c c (shown in Figs. 8, 9, and l0) and when the rivets k 7c are fastened in place, my device is complete, and upon inserting lever e e in mortise oZ, Fig. 3, as shown in Figs. l and 5 and in place in Figs. 2 and 6, said lever (shown in Fig. 6) is raised, with cross-pin g ginserted in fulcrumnotches f f, and drawn forward until the stroke drives for the distance permitted by the fulcrum ff. Said lever e e is advanced to successive notches and the same movement repeated until the desired expansion is obtained. Similar reverse motion of lever e e unlocks the form by driving the wedge-bar back to position, as shown in Fig. 6. Said wedge-bar is arrested by lugs Z Z, preventing escape from said parallel bars a a.

My device is operated in the ordinary printers chase and may be placed next to the type at both bottom and side of the imposed form, thereby obviating the necessity for the IOO lock-up of the imposed form by the simple and rapid operation of one quoin at bottom and one at side. The parallel bars always remain stationary during the operation ot' locking np the form.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination in a quoin, of two parallel bars, a wedge-bar mounted therewith, notches in said bars, and a mortise in said wedge, substantially as described.

2. The combination in a quoin, of two parallel bars, a wedge-bar located between said parallel bars, means for securing them together, a mortise in said wedge-bar, and grooves in said parallel bars on each side of said mortise and in line with each other, substantially as described.

3. The combination in a quoin, of two parallel bars, a wedge mounted between theni and means for securing said parallel bars and wedge-bars together, a mortise in said wedge, notches on each side of said mortise in said parallel bars substantially in line with each other, and a lever having a part adapted to enter the mortise and a pin on each side of it engaging with said notches, substantially as described.

4f. The combination in a quoin, of two par*- allel bars provided with dovetails on their inner sides, with a wedge-bar made in two pieces arranged to lit over said dovetails between said bars and hold the latter together, substantially as described.

WILLIAM H. LYNCHARD.
